Gross profit is what remains of a company's sales after subtracting the direct cost of producing or buying what it sold. The SEC's guide to financial statements describes it as net revenue minus the cost of sales, and calls it "gross" because other expenses, such as rent and wages, have not yet been deducted.
Formula
gross profit = net sales − cost of goods sold (COGS)
Net sales is revenue after discounts and returns. COGS covers direct costs such as materials, packaging and inbound shipping.
Example
A shop sells $12,500 of goods that cost $4,500 to buy and pack. Gross profit = 12,500 − 4,500 = $8,000. Divided by sales, that is a gross margin of 64%; divided by cost, it is a markup of 177.8%.
Gross profit vs net income
Gross profit stops after direct costs. Net income also removes operating expenses, interest and tax, so it is always lower or equal. The profit calculator shows both, and the guide on how to calculate profit margin works through the full chain.
